Recently I used it for my implementation, so here is my code.

You can do that by creating a new style in the styles.xml file:

<style name="question_dialog" parent="@android:style/Theme.Holo.Dialog">
    <item name="android:windowTitleStyle">@style/question_dialog_title</item>
</style>

<style name="question_dialog_title" parent="android:Widget.TextView">
    <item name="android:background">#5cc5cc</item>
    <item name="android:textSize">21sp</item>
    <item name="android:textColor">#ffffff</item>
</style>

and then, when you create your Dialog object, you wanna use this constructor:

answeringDialog = new Dialog(this, R.style.question_dialog);

the output is:
